Richard Sloan from the University of Michigan was first to document what is referred to as the "accrual anomaly". His 1996 paper found that shares of companies with small or negative accruals vastly outperform (+10%) those of companies with large ones.
Deep Fission's Sloan Ratio for the quarter that ended in Dec. 2025 was -194.03%.
Warning Sign:
When sloan ratio (-194.03)% higher than 25% or lower than -25%, earnings are more likely to be made up of accruals.
As of Dec. 2025, Deep Fission has a Sloan Ratio of -194.03%, indicating earnings are more likely to be made up of accruals.
A former University of Michigan researcher, Richard Sloan's 1996 paper found that shares of companies with small or negative accruals vastly outperform (+10%) those of companies with large ones. In fact, for the 40-year period between 1962 and 2001, buying the lowest accrual companies and shorting the highest accrual companies resulted in an average annual compounded return of 18%, more than double the S&P 500's 7.4% annual return over the same period.
If the Sloan Ratio is between -10% and 10%, the company is in the safe zone and there is no funny business with accruals.
If the Sloan Ratio is less than between -25% and -10% on the negative side, and between 10% and 25% on the positive side, this is a warning stage of accrual build up.
If the Sloan Ratio is less than -25% or greater than 25%, and this ratio is consistent over several quarters or even years, be careful. Earnings are highly likely to be made up of accruals.
As of Dec. 2025, Deep Fission has a Sloan Ratio of -194.03%, indicating earnings are more likely to be made up of accruals.
